### **About the Special Issue Editor**

**Rachid Touzani** is full professor of Applied Mathematics at the University Clermont Auvergne (Clermont-Ferrand, France). He was born in K´enitra, Morocco in 1955. He received a M.S. degree from the Universite´ de Franche Comt´e, Besanc¸on, France, in 1979, and a Ph.D. degree from Ecole Polytechnique F´ed´erale de Lausanne (EPFL), Switzerland, in 1988. R. Touzani started his scientific career as a scientific researcher at the EPFL from 1982 to 1992, where he contributed to and conducted research projects in computational fluid dynamics and industrial applications involving electromagnetic processes. Since 1992, R. Touzani has continued his research on eddy current applications from both numerical and theoretical aspects. He was the head of the Mathematical modelling and engineering department at the Polytech Clermont Engineering School. R. Touzani is the author of more than 100 research articles and conferences and is coa-uthor of a textbook on mathematical modelling of eddy currents.

### **Preface to "Finite Elements and Symmetry"**

As a numerical method for the approximation of solutions of partial differential equations, the finite element method has long since proven its efficiency, flexibility, and practicability. Specific issues in the numerical solution have been addressed using this method, such as some qualitative properties of solutions. Among these properties, positivity, regularity, and symmetry are included.

According to the research area covered by the journal *Symmetry*, this Special Issue gathered some publications relative to symmetry in finite element analysis of partial differential equations. This topic is poorly represented in the finite element literature and our objective was to compensate for this lack. Symmetryappearsundervariousaspects:


This Special Issue, entitled Finite Elements and Symmetry, aimed to collect various studies related to this topic to enrich the finite element literature from this aspect.
